C. dessau,

The invention consists broadly in the employment of a slidably mountedplate.

movable Wi' h the lever engaging forks and provided with a depressionfor receiving a plate .locking bolt controlled by a suitaole lockingmechanism.

With the above mentioned and other olojects in. view, the inventionconsists lin the novel construction and combination of partsixereina'ter described`n To more -Sully comprehend the invention,reference is directed to the accompanying drawings, wherein,

Figure l, is a vertical sectional view of the preferred embodiment of myinvention v taken on the line 'l-l of Fig. 2.

2 is a broken top plan viev, of the cons uction illustrated in Fig. l.,

"ring more particularly to the several the drawings, wherein likecharacreference designate corresponding parte. l. indicates a suitablecasing Within the Wall 2 ot which is provided parallel operative slots3, connected by a 'eri selective slot 4;, the arrangement oi' the. slotsproviding what is commonly I termed an til-slot guide for shift levers.

leztendiug transversely of the casing l, below. and preferably parallelwith the selec- 'tive opening is a suitable shaft 5, rotatably mountedin bearings, and rotatable about and extending upwardly from the samethrough slot is a lever 6, normally maintained Within said slot by thesprings 7, positioned on either sido thereot' and prefer ably supportedat their lower ends on said 3 shaft.. i y

1Fositioned one at cach side of said lever and one mounted at lower end#to rotate `with said sli-att and one mounted to rotate about said shaft5, are the lever engaging torito extending upwardly in said casing 1,and terminating one immediately beneath the respective slots 3, at eachside .ot said selective opening; si, thus it ytvill be apparent thatlateral movement ot the. lever t, through the slot e will cause the sameto be received in the upper end of one of said fortis 8, and

when in such position it operative movement the upper ends of therespective lever engag-y ing forks A8, whereby' movement by the lever ota lever engaging fork longitudinally of its cooperating sot 3, willcause longitudinal movement of the plate 9, associated therewith.' f

At a point remote from said pockets 1l, the locking slide plates 9 areprovided in their adj acent inner edges with semi-circular out outs ordepressions 12, adapted for receiving the locking surfaces 13 ot' arotatable slide plate locking bolt lll, projecting downrom the undersideof a rotatable cup 15 to a point between said plate 9. The el ide platelocking bolt is provided on opposite sides with ilat faces 16, adaptedwhen the bolt is rotated to aline said 'laces with the correspondingedges ot the locking slide plates 9, to permit tree longitudinal move'-ment oi' said plates through the operation ot -said lever 6, but on therotation of said locklng bolt 14, to cause the-surfaces 13 thereof toseat Within the depressions 12, the plates are precluded fromlongitudinal movement, thereby preventing operative movement of tbelever 6, longitudinally of the slots 3. lt

is desirable to control the rotation ot the locking bolt le by asuitable loclr controlled.

mechanism, and for purposes of illustration,

suitable seat 522, at one sideof theicu'p 15;` ivhen the bolt 14e, isrotated to locked position, as in Fig. 2 of the drawings, thereby`preventing rotation of the cup l5, and the oit 14, except by therotation of the tumbler 18, to Withdraw the end of the pin 2l from arecess 22, at which time, the cup is free to rotate to remove thesurfaces 13, of the bolt ll, depending therefrom, frdrn the depresLsions l2. The locking of the .plates 9 by the bolt ld is accomplishedpreferably lthrough the rotation of the cup 15, by the manuallycontrolled handle 23.

Having thus described my invention, what li claim is:

i. ln combination with a pivotally mounted lever, a plate provided withparallel slots for guiding the movement of saidlever and parallel slots,a' pair or parallel spaced through which said lever extends, said platebeine provided With a slot connecting said .parilel slots,. a pair' ofparallel spaced plates, one positioned beneath each parallel slot andyformed on their adjacentA edges with` a seat for permitting lateialmovement of the lever into said parallel slots, means for supportingsaid plates to permit longitudinal sliding movement thereof, and a Sillock controlled mechanism positionedl -between -said plates for,simultaneously locking the same from movement.

ln combination with a pivotally mounted 'lever, a plate provided withparallel slots -for guiding the v.movement of said lever andf throughvvlniich said lever extends, said plate being provided with a slotconnecting said parallel slots, a pair of parallel spaced plates, onepositioned beneath each parallell slot and formed on their adjacentedges with a seat for receiving said lever when moved into saidparallelslots, means for supporting said plates to permit longitudi-A nalsliding movement thereof, and a rotatable lock controlled mechanismcarried by said guide plate and extending downwardly therefrom' to apoint between said plates and capable of operative movement for :escasossimultaneously locking said platesjljroni longitudinal movement. 1

4.. In combination with a pivotally mounted lever, a plate provided withparallel slots for. guiding the movement of said lever and through whichsaid lever extend said plate beingprovided 'with a slot connecting saidparallel slots, a pair of parallel spaced plates one positioned beneatheach parallel slot and each formed on its inner edge with a seat andsuitable depressions, said seats adapted for permitting lateral movementof said lever into said parallel slots, .means for supporting saidplates to permit iop itudinal movement thereof, and a lock controlledmechanism for reception within 'said depressions for locking said platesfrom longitudinal sliding movement.

5. In combination with a pivotally mounted lever, a plate provided withparallel slots for guiding the movement of said lever and through whichsaid lever extends, said plate being provided With a .slot connectingsaid parallelA slots, a` pair of parallel spaced plates one positionedbeneath each parallel slot and each formed on its inner edge Witha seatand suitable depressions, said seats adapted for permitting lateralmovement of said lever into said parallel slots, means for supportingsaid plates to permit longitudinal movement thereof, and a rotatablelock controlled mechanism extending between said plates and capable ofoperation for reeeption within said depressions to simultaneously locksaid plates from movement.

6. In combination Witlia pivotally mounted lever, a plate provided Withparallel guideslots and through which said lever eX- tends, said platebeing further provided with a slot connecting said parallel slots, apivotally mounted lever engaging fork, positioned beneath each of saidparallel slots and with which saidllever is capable of selectivemovement for operating said selective fork longitudinally of itscoperating slot, a pair of parallel spaced plates positioned. beneathsaid'guide plate. and each `adapted to receive one of said forks, andmovable longitudinally on 'the movement of its associated fork, meansfor slidably supporting said plates and a rotatable lock controlledmechanism for engaging said plates to lock the same from longitudinalmovement.
